Retroreflectometer for Road Marking Retroreflectivity Measurement (RL / R’ Value Testing Device)
The Retroreflectometer is a professional instrument used to measure the retroreflective performance of road markings under night-time and low-light conditions. It evaluates the retro-reflective luminance coefficient (R’), also known as specific luminance of road markings, expressed in mcd·m {²·lx {¹. This device is essential for ensuring road visibility, safety compliance, and quality control in traffic infrastructure.Performance & Benefits
- Accurate measurement of retroreflective luminance coefficient (R’)
- Ensures compliance with international road marking standards
- Enhances night-time road visibility and safety
- Supports quality control for new and existing road markings
- Portable and suitable for field inspections
